Welcome to the forum.

I've already asked him once but you know what users are like.

Can I suggest that you add your car spec to your signature as it will save users asking every time, if you know the engine code that will also be great? Oh you can't do this of a phone. http://www.volkswagenforum.co.uk/f26/adding-your-car-spec-5119.html

I am surprised there is no power feed at the ECU relay because it is fed directly from the battery with no fuses by two thick 4-mm red wires which separate in the harness from the 10-mm thick red wire and go into the fusebox at two separate points but both providing the main feed. Use a multimeter with one connector to a good earth and the other into socket 4 of the 109 relay position (which is location 3).Putting a jump wire across sockets 4 and 6 should power up the ECU. If there is no power then go and look at the battery terminal.

I would recommend starting your own post with full details of the van as yours will be a T5 and the electrical system is completely different.
